MACHINE FOR WIRING PAPER INTO BUNCHES.

SPECIFICATION forming'part of Letters Patent No. 238,198, dated February22, 1881.-

Application filed September 2, 1879. I

To all whom it may concern:

Be it known that CHARLES P. S. WARD- WELL, deceased,;did:invent a newand I mproved Machine for Wiring Paper, and I,-MAR- CIA B. WARDWELL, ofLake Village, in the county of Bclknap and State of New Hampshire,administratrix of the estate of the said CHAR-LES P. S. WARDWELL, dohereby declare that the following is a full and exact description of thesaidmachine, reference being had to the accompanying drawings, makingpart of this specification Figure 1 being a front view of the machine;

' Fig. 2, aside view of the same; Fig. 3, a horir5 zontal section in aplane indicated by the line :0 m, Fig. 1; Figs. 4, 5, 6, 7, 8, and 9,views of parts in detail; Fig. 10, a view of the paper perforatingneedle enlarged.

Like letters designate corresponding 2c in all of the figures.

The object ofthis invention is to insert a loop of wire, or itsequivalent, through a thick bunch-as a ream, more or less-of paper, andto twist or otherwise secure the ends of the in- 2 5 serted wiretogether by an automatic operation, and to effect this with successivebunches rapidly and at slight expense.

The entire organization of the machine is believed to be new, and thespecific features of 0 novelty therein will be designated in order. Anysuitable stand or frame, A, as represented or otherwise, is employed.The prime drivingshaft B, locatednear the top, receives its power fromthe provided source by a belt 3 5 running on the pulley a thereof.Suitable gearwheels, b c, communicate a slower motion, as desired, fromthis shaft to another shaft, 0, by which the several operative parts ofthe ma. chine receive their movements.

Upon the shaft 0 is a crank and cam disk or wheel, D, for producing thepaper-perforatin g and. wire-inserting movements.

A crank-pin, d, on the face of the disk D, operatesa connecting-rod, E,which ,is pivoted at 4 5 its lower end to a vertical] y-slidin gcarriage or head-block, F, to the lower end of which is secured a hollowor tubular needle, G, that perforates the bunches of paper byitsdownward motion, and opens a passage for the wire parts eral dischargeof the wire therefrom threaded and carriedtherein. The paper at the timerests on a table orsupport, H, which has a hole, 6, Fig.4, through itfor the needle to pass down into or through, the said hole opening toone edge of the table by a side slot, whereby the wire, when passedthrough the 5; table, is carried out without withdrawing, for securin gthe ends of the piece formin g the loop together, while the paperremains on the table. As the needle is required to remain stationary fora time in its lowest position, the upper end of the connecting-rod E hasa long slotbearing, f, to work on the crank-pin d. The length of thisslot is equal only to about half the diameter of the sweep of thecrank-pin, to allow the requisite extent of vertical movement of theneedlecarrier F to be produced thereby.

A cam, g, on the face of the disk D forces downa vertically-sliding bar,h, which carries a presser-plate, I, to hold the bunches of papercompactly on the table, and allow-the needle to be withdrawn therefromin its upward movement. The presser-plate is also perforated and notchedor slotted at one edge, to allow the passage through of the needle andthelatwhen securing its ends together. The wire, having first beenstraightened and wound upon a reel of large diameter, first passes fromthe reel down through a friction-clamp, t, then through two dogs, J andK, in succession, then into and through the needleG. Thedogs J and K bytheir peculiar construction and operation feed the wire downin properlengths at successive movements in the following manner: The lower dog,J, is attached to the nee- 8 dle-carrier F,and has, of course,corresponding and simultaneous movements therewith. It is constructedwith two guide eyes or holes, j j, and between them apivoted catch, it,as shown most clearly in Fig. 5 ,whicl1 clamps the wire between its end,made sharp or chiseledged, and the back plate of the dog. It is so hungand pivoted that when the dogdescends it swings upward till its sharpend clamps against and holds the wire, the outer 5 end thereof beingcounterweighted, so as to tend to hold against the wire; but when thedog ascends it frees the catch from its hold on the wire and slidesthereon. As the needle-carrier descends, this dog draws the wire,already reaching through the entire length of the needle, down with ittill the needle approaches itslowest position, when the outer end of thedog-catch strikes a fixed part, I, of the frame, and, being raisedthereby, loosens the holding end of the catch and sets the wire free.Just then the upper deg, K, which is constructed and operates in thesame way as the dog J, begins to descend and moves the wire down stillfarther, so that it will project sufficiently below the needle and thebunch of paper for connecting with the other part above the paper andform a loop of the requisite size. This dog K is mounted on a separatesliding bar, L, which is forced down by a cam, m, on the periphery ofthe disk D, and its return upward movement is effected by acounterspring, at, or its equivalent. Its catch is re-- leased from thewire at the close of its downward movement by striking the top of thedog J, which at that time just begins to ascend with the needle. Atrough or support, M, below the table receives the lower end of thewire, and sustains the part out off from the wire stock to form thesuccessiveloops until the twisting or end-uniting mechanism is broughtinto action.

The severing of the wire to form the loop, which is the next operation,and is efi'ected as soon as the needle ascends far enough to per- V mitit to be done below the same, is performed by a mechanism substantiallyas follows: The cutting-0E device, as shown in Fig. 3, consists ofshear-blades N N, which have a longitudinally-sliding movement in apart, 0, of the frame, so as to retire out of the way of the needle asthe same descends, but to advance at the proper time, and then cut offthe wire.

. To this end one blade, N, slides in its way endwise and has no othermovement. The other blade, N, is pivoted to and carried by the slidingblade N, and has a lateral movement to shear off the wire. To producethese movements-of the shear-blades, a vertical shaft, 0, is mounted onthe frame in a proper position, and receives its motion from the shaft 0by suitable bevel-wheels p p, of equal size, so that the shaft makes onerevolution at each entire movement of the needle and other operativeparts. On this shaft is acam, g, which moves the sliding blade Nforward, the return movement being effected by a spring (shown by dottedlines in Fig. 3) acting on a push-bolt, 1". Another cam, s, on the shaft0 swings the shear-blade N, to cut off the wire at the proper moment.Its reverse opening movement is also effected by a counter-spring, u.

The next operation is to bring the ends of the severed wire aroundtogether, and to insert the same between the twisting-jaws P P. This iseffected by two forks or hook-fingers, Q Q, which turn on two shafts,Figs. 1 and 6, bearing, respectively, cog-wheels u it, geared together,and one also geared into a rack, R,

whereby the fingers are vibrated in the proper arc of a circle, onelimit of which is indicated by the position of the fingers in full linesback of the wire in Fig. 1, and the other by the position of the fingersin dotted lines in the same figure. The reciprocating motion of the rackR to produce this vibratory movement of the fingers is produced by acrank-lever, S, one arm of which engages with the rack-bar, and theother arm is actuated by counter-cams o c on the shaft 0. The fingersbring forward the ends of the wire and insert them between thetwisting-jaws P P, which at the time are in a vertical position, asindicated in Fig. 7 and at right angles to the position shown in Fig. 1,which is the position of the same after the twisting of the wires, andwhen the loopwire is to be withdrawn therefrom and the wired paperbunches from the machine.

The construction and operation of the twisting apparatus aresubstantially as follows: The twisting-jaws P P are mounted on ahorizontal shaft nearly in line with the center of the vertical shaft 0,and are pivoted thereto, as shown. A sliding pin or bolt, T, located inthe center of the jaw-shaft, bears a cross pin or bar, 20, which pressesagainst the heels of the pivoted jaws P P. When the jaws are in ahorizontal position, ready to receive the ends of the wire, the pin T isheld back by a spring, so as to leave the jaws P P just far enough opento admit the ends of the wire. As soon as these wire ends are inserted,a cam, U, on the shaft 0 strikes the projecting end of the pin T, and,pushing it forward, closes the jaws against the wire and holds the sametill the twisting is performed. A little projection on the middle of theface of one jaw enters a notch or depression in, or projects over, theother jaw, as shown in Fig. 8, thus closing the space between the jawsand preventing the ends of the Wire from crossing each other as they arebrought into place, and holding them in the exact position required. Therevolving of the jaws for twisting the ends of the wire together aftertheyareinserted and the j aws are clamped against them is effectedinstantaneously by independent power, while the shaft 0 and cam U remainin nearly one position and hold the jaws clamped together. To effectthisapinion, 11 is secured on the jaw-shaft, and into this gears acog-wheel,V, of larger diameter, so as to give as many turns of thewiretwisting shaft as desired by giving only a part of one revolution tothe cog-wheel shaft 2. On this shaft is adrum or pulley, 1, around whichwinds a strap, cord, or chain, W, the other end of which is connectedwith a spring or weight, X,forturnin g the cog-wheel with the necessaryforce to twist the wires. On this shaft, also, is a bevel-gear wheel, 2,which gears into another bevel-gear wheel, 3, on the vertical shaft 0,and consequently turns the drum-shaft constantly as the machinecontinues to operate; but the drum is attached to a collar or sleeve,which turns freely on the said shaft when'not coupled to the gear-wheel2 or its shaft direct. This coupling is effected by means of a slidingpin, 4, Fig. 9, kept pushed against the said collar bya spring, 5, andis thereby caused to catch against a shoulder orin ahole,6,in the endthere of. The drum is thus ordinarily kept coupled to its shaft, so thatas the shaft 0 revolves, the cog-Wheel Vand drum 1 revolve and wind thedrum strap or cord W on the drum, thereby drawing upon the spring orweight. By the time that the fingers bring the ends of the wire to thejaws P P the shaft 0 has turned the said jaws around and brought theminto a vertical position, ready to receive the ends of the wire, whichare then inserted by the fingers, and the cam U clamps them therein.Just then one of the cogs of the bevel-gear wheel 3 strikes aprojection, 7, on the sliding pin 4, which lies between two cogs on thebevel-gear wheel 2, into which the said bevel-wheel 3 gears, and slidesthe pin back sufiiciently to uncouple it from the drum, whereupon thespring or weight X acts to turn the drum through the strap or cord Wwound thereon, and consequently revolves the jaws P P and instantlytwists the ends of the wire together. A projection block or bar, 8, isfixed inside of the wire ends, just back of where the twist is made, toprevent the twist from being made too far from the ends. A projection,9, on the cog-wheel V strikes an elastic stop, Y, when the strap or cordW has suffioiently turned it, and holds it there amoment, leavingthejaws PP, as shown in Fig. 1, in a horizontal position long enough toallow the ready removal of the wire loop therefrom and the wired bunchor package of paper from the machine. By this time the cam U has passedalong and allowed the jaws to open and set the wire free to bewithdrawn. A friction-brake, Z, bears lightly against the periphery ofthe drum 1, to keep the same in its proper position-at all times.

The needle G is not only tubular from end to end, but has a notch at oneside from the tubular aperture at the point, so that the Wire may turntoone side without injuring the point. This notch does not interfere withpenetrating the paper. WVhat'I claim as the invention of the late OHAs.P. S. WARDWELL is- 1.
